qt script signal handler

[wookoon]

Recent I look at the "qt script signal handler",This project available creating signal in qt script.

this is some code they provide.

Script-to-script

SignalBaseClass = function() {
    this.test = "signalBaseClass";  
    this.baseSignal = signal();  
    this.intSignal = signal();  
};  
SignalBaseClass.prototype.emitBaseSignal = function() {  
    this.baseSignal.emit("emitBaseSignal from " + this.test);  
};  
SignalBaseClass.prototype.emitBaseSignal2 = function() {  
    this.baseSignal.emit("emitBaseSignal2 from " + this.test);  
};  
SignalBaseClass.prototype.emitBaseIntSignal = function() {  
    this.intSignal.emit(123);  
};
 
testSlot = function() {
    print("testSlot arguments count: " + arguments.length);  
    for (var i = 0; i < arguments.length; ++i)  
        print("testSlot first argument: " + arguments[i]);  
};
 
SlotClass = function() {  
    this.name = "slotClass";  
};
 
SlotClass.prototype.slot = function() {  
    print(this.name + " slot arguments count: " + arguments.length);  
    for (var i = 0; i < arguments.length; ++i)  
        print(this.name + " argument(" + i + ") " +  arguments[i]);  
};  
baseObject = new SignalBaseClass();  
slotObject = new SlotClass();  
baseObject.intSignal.connect(testSlot);  
baseObject.emitBaseIntSignal();
 
signalObject = new SignalClass();  
signalObject.baseSignal.connect(testSlot);  
signalObject.newSignal.connect(slotObject, slotObject.slot);  
signalObject.emitNewSignal();

SignalBaseClass = function() {
    this.test = "signalBaseClass";  
    this.baseSignal = signal();  
    this.intSignal = signal();  
};  
SignalBaseClass.prototype.emitBaseSignal = function() {  
    this.baseSignal.emit("emitBaseSignal from " + this.test);  
};  
SignalBaseClass.prototype.emitBaseSignal2 = function() {  
    this.baseSignal.emit("emitBaseSignal2 from " + this.test);  
};  
SignalBaseClass.prototype.emitBaseIntSignal = function() {  
    this.intSignal.emit(123);  
};

testSlot = function() {
    print("testSlot arguments count: " + arguments.length);  
    for (var i = 0; i < arguments.length; ++i)  
        print("testSlot first argument: " + arguments[i]);  
};

SlotClass = function() {  
    this.name = "slotClass";  
};

SlotClass.prototype.slot = function() {  
    print(this.name + " slot arguments count: " + arguments.length);  
    for (var i = 0; i < arguments.length; ++i)  
        print(this.name + " argument(" + i + ") " +  arguments[i]);  
};  
baseObject = new SignalBaseClass();  
slotObject = new SlotClass();  
baseObject.intSignal.connect(testSlot);  
baseObject.emitBaseIntSignal();

signalObject = new SignalClass();  
signalObject.baseSignal.connect(testSlot);  
signalObject.newSignal.connect(slotObject, slotObject.slot);  
signalObject.emitNewSignal();

the function qScriptDisconnect(). will lead to errors cause the parameter.
